If none are configured, then use the adapters command to determine which adapters are in use. The tnsnames.ora and sqlnet.ora files are located in the default network administration directory on the client system. Performing a successful loopback verifies that Oracle Net is functioning on the database server. The most efficient way to evaluate error codes is to find the most recent nserror entry logged, as the session layer controls the connection.

The TNSPING utility determines whether a service, such as a database or other TNS services, on a Oracle Net network can be successfully reached. If the time out occurs before the IP address can be retrieved by the database server, then enable listener tracing to determine the client that made the request. You need to check what address your listener is using too though. A generated ID is created by Trace Assistant if the packet is not associated with any connection, that is, the connect packet is overwritten in the trace file. Oracle Connection Manager CMGW (Oracle Connection Manager gateway) process, Oracle Connection Manager CMADMIN (Oracle Connection Manager Administration) process.

The trace file names are distinguished from one another by their sequence number. In some cases, these errors are caused by the same conditions which cause TNS-00510, TNS-00519, TNS-12540/ORA-12540, TNS-12549/ORA-12549 errors. See other computers or servers on the Microsoft network. If you receive the following errors, then ask your Database Administrator to assist you: A loopback test uses Oracle Net to go from the database server back to itself, bypassing the Interprocess Communication (IPC). Listener subscribes to the Oracle Notification Service (ONS) node down event on startup if the ONS configuration file is available. This client could be attempting a denial-of-service attack on the listener.

This error occurs when a client fails to complete its connection request in the time specified by the INBOUND_CONNECT_TIMEOUT_listener_name parameter in the listener.ora file. That blocker session is itself occupied in a long-running activity (or its own hang) which prevents it from releasing the shared resource needed by the authenticating session in a timely fashion. The name of the trace file for the server is svr_pid.trc. The Trace Assistant can work with ADR tracing files and non-ADR tracing files.
